    Deeper Dive

    Who can you trust to guard your precious coins? Your loyal coin-eating dragon, that’s who! It turns out, the world’s coolest piggy bank is actually a dragon bank! Make your very own mechanical dragon and turn your spare change into savory savings.

    Learn about simple electric circuits, gears, and other mechanisms as you construct the motorized model from durable plastic building pieces. When you place a metal coin in your dragon’s mouth, the wings flap and the jaw snaps shut as it automatically gobbles up the tasty treat.

    The full-color experiment manual provides clear step-by-step assembly instructions and explains how the inner workings turn an electrical signal into movement. Your coins stay stored in the treasure chest until you’re ready to spend — just release the clasp to open the door and watch your treasure pour out!

    • Build a own mechanical coin bank that’s shaped like a dragon and teaches about electric circuits!
    • Automatic and button-free, coins settle into the bank as soon as they’re placed, completing the circuit
    • Combines a unique, hands-on building toy with authentic science lessons
